Unable to connect: Adaptive Server is unavailable or does not exist

Hello,

This is my first post to this list. I am a new user of freetds. Here is my scenario. I am trying to connect from a Redhat ES3 (old,yes I know) box to a MSSQL Server 2005 databse.

I have installed the latest stable version of freetds on the Linux box. I run the tsql command like this:

Tsql  -H my.host.ip.address -p 1443 -U sa

The result is this:

tsql -H  my.host.ip.address -p 1443 -U sa
locale is "en_US.UTF-8"
locale charset is "UTF-8"
Password:
Msg 20009, Level 9, State -1, Server OpenClient, Line -1
Unable to connect: Adaptive Server is unavailable or does not exist
There was a problem connecting to the server


I have tinkered with older versions of freetds, had the freetds-devel installed and installed unixodbc. I may have missed some steps and am missing parts that are needed.

Could someone point me in the right direction so that I don't continue spinning my wheels here? Thanks.
